Diamond Sutra: Chapter 29

The Buddha said:

“Subhuti, if any person were to say that the Buddha is now coming or going, or sitting up or lying down, they would not have understood the principle I have been teaching. Why? Because while the expression ‘Buddha’ means ‘he who has thus come, thus gone,’ the true Buddha is never coming from anywhere or going anywhere. The name ‘Buddha’ is merely an expression, a figure of speech.”
